Hey all, I have been upgrading the components in my laptop (cheaper than buying a new one), and my last thing ot upgrade is the battary. I have a 3 year old Acer Aspire, and I'm lucky to get 2 hours out of it with minimal use (no videos). I know I can get new batteries (via microcenter, etc), but will the new ones be that much of a performance booster? Thanks!
